The Ballista Bolts are a bunch of arrows that increase the chance of a critical strike. When used with the Ballista, the ability " Artillery Strike" is activated. If the attack is a critical strike, normal damage is increased by 100%.
Every Ballista Bolt comes with a Ballista in weapon shops around the world. Usually, archery instructors would teach their pupils on how to use the ballista during advanced archery class.
